Connector assembly including terminal protection features

Abstract

A connector assembly includes a housing having a housing base, a housing body protruding from the housing base, and a first housing protrusion provided inside the housing body. A protection part includes a protection base facing the housing base, a protection body protruding from the protection base, and a first protection arm extending from the protection body for engaging with the first housing protrusion. An insertion part of the assembly includes an insertion body for inserting inside of the protection part, and a first insertion protrusion protruding from the insertion body to interfere with the first protection arm. The first insertion protrusion deforms the first protection arm and causes the first protection arm to disengage from the first housing protrusion while the insertion body is inserted inside of the protection part.

       2. The connector assembly of  claim 1 , wherein the insertion part includes a first surface facing the first protection arms, the first insertion protrusions protrudes from the first surface, and the first protection arm is movable in a direction intersecting with a normal direction of the first surface. 
     
     
       3. The connector assembly of  claim 2 , wherein the first protection arm is movable in a direction parallel to the first surface. 
     
     
       4. The connector assembly of  claim 1 , wherein the protection base comprises a cut part recessed from an edge portion toward the center for receiving the pair of first housing protrusions. 
     
     
       5. The connector assembly of  claim 1 , wherein the first housing protrusion includes:
 a first housing protrusion body protruding from the housing base in a first direction; and 
 a first housing protrusion head protruding from an end portion of the first housing protrusion body in a second direction intersecting with the first direction to interfere with the first protection arm. 
 
     
     
       6. The connector assembly of  claim 1 , wherein the first protection arm includes:
 a first protection arm body extending from the protection body in a first direction; and 
 a first protection arm head protruding from the first protection arm body in a second direction intersecting with the first direction to interfere with the first housing protrusion. 
 
     
     
       7. The connector assembly of  claim 6 , wherein a portion of the first protection arm head supported by the first housing protrusion does not overlap a portion of the first protection arm head interfering with the first insertion protrusion. 
     
     
       8. The connector assembly of  claim 6 , wherein the first protection arm head includes a first inclined part having a height protruding from the first protection arm body increasing along an insertion direction of the insertion part. 
     
     
       9. The connector assembly of  claim 8 , wherein the first protection arm head further includes a second inclined part having a height protruding from the first protection arm body decreasing along the insertion direction and that does not overlap the first housing protrusion in the insertion direction. 
     
     
       10. The connector assembly of  claim 9 , wherein a width of the second inclined part is less than a width of the first inclined part. 
     
     
       11. The connector assembly of  claim 1 , wherein the protection part further includes a second protection arm extending from the protection body and spaced apart from the first protection arm. 
     
     
       12. The connector assembly of  claim 11 , wherein the insertion part further includes a second insertion protrusion interfering with the second protection arm protruding from the insertion part. 
     
     
       13. The connector assembly of  claim 12 , wherein the housing further includes a second housing protrusion protruding from the housing base, the second protection arm is prevented from being deformed by the second housing protrusion while the protection part is raised a predetermined distance from the housing base. 
     
     
       14. A connector assembly, comprising: a housing including a housing base, a first housing protrusion provided inside of the housing, and a second housing protrusion protruding from the housing base and having a height lower than a height of the housing body; a protection part including a protection base facing the housing base, a protection body protruding from the protection base, a first protection arm extending from the protection body for engaging with the first housing protrusion, and a second protection arm extending from the protection body and positioned spaced apart from the first protection arm; and an insertion part inserted into the protection part and including a first insertion protrusion protruding therefrom for interfering with the first protection arm, and a second insertion protrusion protruding from the insertion part for interfering with the second protection arm; wherein each of the first insertion protrusion and the first protection arm is provided in a pair, the pair of first insertion protrusions deforming the pair of first protection arms toward each other. 
     
     
       15. The connector assembly of  claim 14 , wherein the first insertion protrusion deforms the first protection arm for disengaging the first protection arm from the first housing protrusion while the insertion part is inserted into the protection part. 
     
     
       16. The connector assembly of  claim 14 , wherein the insertion part includes a first surface facing the first protection arm and a second surface facing the second protection arm, the first insertion protrusion protruding from the first surface. 
     
     
       17. The connector assembly of  claim 16 , wherein the first protection arm is movable in a direction parallel to the first surface, and the second protection arm is movable in a direction normal to the second surface. 
     
     
       18. The connector assembly of  claim 14 , wherein the first housing protrusion includes:
 a first housing protrusion body protruding from the housing base in a first direction; and 
 a first housing protrusion head protruding from an end portion of the first housing protrusion body in a second direction normal to the first direction for interfering with the first protection arm. 
 
     
     
       19. The connector assembly of  claim 14 , wherein the first protection arm includes:
 a first protection arm body extending from the protection body in a first direction; and 
 a first protection arm head protruding from the first protection arm body for interfering with the first housing protrusion.
